Texte intégralNatural products (NPs) have declined in popularity since the introduction of synthetic small molecules several years ago. Many are the reasons behind this choice, such as difficulties in access and supply, complexities of NP chemistry and the advent of combinatorial chemistry. However, NPs offer many interesting properties compared to conventional synthetic molecules, which confer both advantages and challenges for the drug discovery process. Usually, NPs are characterized by a higher number of sp3 carbons and stereogenic centres, large scaffold diversity and structural complexity. With half of the drugs approved by the FDA since 1994 being NPs or hemisynthetic derivatives and the recent stagnation in new drug research and development, it is becoming more and more evident that NPs should be reintroduced in the drug discovery process as a source of inspiration.Therefore, many strategies are now emerging for the construction of nature-inspired chemical libraries, such as “top-down” and “bottom-up” strategies. In “bottom-up” approaches, complexity is created starting from simple building blocks. On the other hand, “top-down” approaches are assumed to make structural modifications to an already complex NP.Our presented work describes two different approaches to enrich the chemical library of our research unit with NP-derived compounds. A “top-down” semisynthetic strategy was planned to obtain derivatives of lactucin and 11β,13-dihydrolactucin, two sesquiterpene lactones extracted from chicory roots. Thirty-six ester derivatives were synthesized in three steps (classical synthesis), together with two amine derivative libraries (using parallel synthesis). All the compounds were then tested against Mycobacterium tuberculosis and some promising hits were found (MICGFP < 1.2 μM). On the other hand, a “bottom-up” strategy allowed the synthesis of two analogues of the known natural antibiotic hygromycin A. This approach started from simple commercially available building blocks and employed a dearomatization strategy in the synthetic process.Together, we explored a broader chemical space, increased the structural diversity of our chemical library and discovered new potential antibacterial hits. Moreover, this work paves the way for the discovery of new antibacterial targets

To characterize the resistance, the experimental model was completely randomized in a factorial design of 10 X 9, determined by the nine races of B. lactucae and their mixture, and the eight lineages of crisp leaf lettuce and the susceptible cultivar Solaris, with four replications.

Sintomas e sinais do míldio foram observados e coletados em plantas de alface (Lactuca sativa) no Distrito Federal. Foi observado o estágio assexual do patógeno (Bremia lactucae). Descrições detalhadas, com observações morfológicas e medidas morfométricas de microscopia óptica do estágio assexual foram realizadas. A patogenicidade do míldio proveniente do Núcleo Rural da Vargem Bonita e seu período de latência, em quatro diferentes estádios de desenvolvimento de cultivares comerciais de alface foram estudados por inoculação artificial em ensaios realizados na Estação Biológica da Universidade de Brasília. Quando observado o “ranking” de suscetibilidade das cultivares nos quatro diferentes estádios de desenvolvimento para o período de latência, observou-se diferentes níveis de resistência entre as cultivares. Além disso, observou-se que a resistência parece aumentar com o desenvolvimento fenológico do hospedeiro. O “ranking” relativo das cultivares não foi afetadopelo estádio de desenvolvimento. _________________________________________________________________________________ ABSTRACT
Symptoms and signs of downy mildew were observed and collected in lettuce plants (Lactuca sativa) in Distrito Federal, Brazil. Only the asexual stage of the pathogen (Bremia lactucae) was observed. Detailed descriptions, including fungal morphology and morphometrics were performed with light microscopy. The pathogenicity of downy mildew, collected in Núcleo Rural da Vargem Bonita, as well as it latent period in four phenological stages of lettuce commercial cultivars were studied by artificial inoculation in experiments conducted at Biological Station of University of Brasilia - UnB. Latent period was useful to separate cultivars by resistance level. In addition, results indicated that genetic resistance to downy mildew in lettuce seems to increase with plant development. The relative ranking of susceptibility among cultivars remained constant in all four phenological stages.
